We divide 809392 by 30
We want to figure out the number of times 809392 can be divided by 30.

On to step 1:
8 divided by 30 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 30

Moving on to step 2:
When dividing 80 by 30, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 60 away from 80, we end up with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 30

Moving on to step 3:
When dividing 209 by 30, we get 6 with a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 180 from 209 and we're left with 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 30

Going ahead to step 4:
If we divide 293 by 30, we get 9 and a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 269.0
Subtract 270 from 293 to get 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 30

Moving on to step 5:
30 can be fit into 239 7 times, resulting in a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 2697.0
The remainder is 29 after subtracting 210 from 239.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 30

Moving on to step 6:
If we divide 292 by 30, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 26979.0
Deduct 270 from 292 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
If we divide 220 by 30, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 26979.7
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
30 goes into 100 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 26979.73
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
100 divided by 30 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 26979.733
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 26979.733 with a remaining 0.001.
